Abstract (en)

[origin: WO9956215A1] A video data recording unit receives input video signal streams from up to 16 cameras (42). The signal streams are selectively converted into digital video signals (56-1, 56-2) and are stored on a data storage device such as a hard disk (62). The apparatus is controlled so that both odd and even signal fields generated by at least one camera are recorded, whereas only odd fields or only even fields generated by the other cameras are recorded. Odd and even signal field streams may be derived from a single stream of demodulated video signals, or from respective demodulation streams.
